Description
Technical field
The present invention relates to a kind of anti-falling safe pick-up unit, being specifically related to a kind of pick-up unit of the anti-falling safe performance for detecting transmission line of electricity.
Background technology
In recent years, constantly accelerate along with China Power developing steps, China Power Grids is also developed rapidly, network system working voltage grade improves constantly, network size constantly expands, the whole nation has defined Northeast China Power Grid, North China Power Telecommunication Network, Central China Power Grid, East China Power Grid, Northwest Grid and south electric network 6 large area electrical network transprovincially, and has basically formed complete long distance powedr transmission Net Frame of Electric Network.Power grid construction has become the Main way of China's power construction, and " 12 " period, China's electric grid investment scale continuous expansion, will build up unified strong intelligent grid to the year two thousand twenty comprehensively, and tentatively realize the target of building world class electrical network.
Along with the development construction of China's electrical network; maintenance and the testing of electric power pylon become more and more important; in the process of current domestic transmission line pole tower operation maintenance high-altitude mobile operational process; staff needs necessary anti-falling from high altitude safeguard measure; existing salvo and scheme can meet the requirement for safeguard protection in the mobile operational process process of high-altitude substantially, thus achieve the safe closed loop protection of work high above the ground.
Transmission line high-altitude mobile operational process, mainly refers in iron tower of power transmission line and the enterprising pedestrian's displacement body of cement pole, upstream or downstream activity.For steel tower; general dependence arranges pin nail or cat ladder carries out displacement; for cement pole; general dependence ascending tool carries out displacement, and in moving process, require that the safety feature of fall arrest realizes real-time, omnidistance protective effect, and no matter operating personnel carries out high-altitude mobile operational process on steel tower or cement pole simultaneously; all must accomplish spiritual high concentration; foot-operated real, hand is grabbed surely, climbs coordination to prevent the burst hidden danger that may occur.
Except power industry also has a lot of other industry; the industries such as such as building, mine, municipal administration, railway, oil, chemical industry, metallurgy, post and telecommunications and high-altitude service sector have work high above the ground; but these industries also have a lot of not enough to the research of anti-falling overhead; substantially proper use of securing band, safety net is mainly emphasized; safety barrier be set and avoid high-rise working etc., not emphasizing the protection in moving process.
Current domestic transmission line of electricity has substantially all installed the safety feature of fall arrest, falling-proof safety device is as the accessory of iron tower of power transmission line, effectively can prevent line maintenance, construction operation personnel are upper, the falling accident of personnel is there is in lower shaft tower process, for circuit homework personnel are climbing in shaft tower process the security protection equipment providing reliable and practical, falling proof device specification operation behaviour is installed, improve operation field safety construction level, although add line construction cost, but in personal safety, there is very big safety guarantee, also the spiritual civilization construction theory that people-oriented has been fully demonstrated, iron tower of power transmission line is installed falling proof device and is had far-reaching social effect.
By capital construction portion of State Grid Corporation of China, exchange Ministry of Construction's result that the part of relevant unit personal investigation economizes 11 Jia Yunjian companies of taking the lead for twice and show, falling proof device all installed by extra high voltage line steel tower.Wherein, 1000kV southeast Shanxi-Nanyang-Jingmen exchanges engineering and installs 1284 cover falling proof devices altogether, is responsible for working service by Shanxi, Henan, 3, Hubei province Yun Jian company; ± 800kV Burner zone-Shanghai DC engineering installs 3149 cover falling proof devices altogether, is responsible for working service by Hubei, Sichuan, Chongqing, Hunan, Anhui, Zhejiang, Jiaxing, Jiangsu, 9, Shanghai province Yun Jian company.Investigation statistics according to 11 province Yun Jian companies and Shandong District draws, in actual moving process, falling proof device uses 1 ~ 3 time every year on average, generally step in tower inspection, monitoring and maintenance process and all need to use falling proof device, this just requires that the equal claimed condition of these falling proof devices is good.
But in use also there are some problems in these falling proof devices installed and used.Such as, self-locking device slides not smooth; Guide rails assembling or run after a period of time, easily occurs distortion, distortion, not straight causing self-locking device not pass through smoothly; Some steering gear turns to dumb, and self locking on partial circle device is heavier, increases workman and bears a heavy burden and labor capacity; Some tower exists K point not easily pass through, have potential danger of falling; Steel strand wires type self-locking device moves, installs need tear open through each support interval, uses inconvenience, reduces operating efficiency; In sleety weather situation, rail mounted falling proof device usually because track icing and not easy-clear, when icing is serious, the situations such as cisco unity malfunction.
Although the domestic research at falling proof device and use are also in the starting stage, due to actual needs, the number of times that falling proof device uses and frequency are more and more frequent, and the safety problem of falling proof device highlights important.In order to effectively detect the performance of falling proof device, the present inventor is according to normal shaft tower falling proof device performance test index, find through long-term observation, research, devise a kind of test unit detecting iron tower falling-proof dropping control device performance, for testing the performance of dissimilar falling proof device, the requirement to the test such as dead load, impact load in " falling-preventing device for pole tower operation " Q/GDW162-2007 standard can be met simultaneously; Thus ensure that falling proof device does not occur to destroy and yield deformation in 15kN dead load, 100kg load impulse test situation.
